Application June 28, 1935, Serial No. 28,966 Renewed December 31, 1936 1 Claim.

This invention relates to a device for cooling and dispensing liquids.

An object of the invention is the provision of a device adapted to be fixed in an opening in a container for liquids which has a pair of compartments in heat-interchange relation with each other with one of the compartments adapted to house congealed carbon dioxide, the other compartment being adapted toreceive liquid from the container, both of the compartments being connected with the container in such a manner that the liquid in one of the compartments is adapted to cause the congealed carbon dioxide to give ofi carbon dioxide gas which is conducted to the container for creating a pressure in the container and forcing liquids in the container into the respective compartment whereby the liquid may be dispensed.

A further object of the invention is the proision of a device for exerting gaseous pressure upon a liquid in a container whereby the liquid will be forced from the container into a compartment which is located in heat-interchange relation with a second compartment adapted to contain congealed carbon dioxide which when converted into a gas will be conducted to the container and exert a pressure on the liquid in the container so that the congealed carbon dioxide may be utilized for the double purpose of not only cooling the liquid dispensed from the container but for exerting sufiicient pressure to cause ready dispensing of the liquid.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless, it is to be'understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications as define no material departure from the salient features of the invention as expressed in the appended claim.

In the drawing:

Figure 1 is a view in elevation partly in section of a device constructed in accordance with the principles of my invention,

Figure 2 is an end view of the cooling and dispensing device,

Figure 3 is a longitudinal vertical section of the dispensing device, and

Figure 4 is a transverse vertical section taken along the line 44 of Figure 1.

Referring more particularly to the drawing, l6 designates a keg or container which is adapted to house a liquid such as beer or the like which is adapted to be dispensed from the container in a convenient manner. This keg is provided with a top H- which seals the liquid in the container from the atmosphere. The top is provided with a bung or plug l2 which is of the usual type and has a central opening as indicated at l3 which is normally closed with a second and smaller plug and this plug is adapted to be forced into the container when a dispensing pipe I4 is forced into the opening i3. V

The dispensing device includes a housing l5 which is divided into two compartments or chambers l6 and I1 by means of a partition l8 which isolates the compartments from each other.

One end of the housing is open and is provided-with closures l9 and 20 which respectively close the ends of the compartments or chambers 55 and H. The cover I9 is secured in place by means of threaded lugs 2| which project from the open end of the housing upon which are screwed thumb nuts 22. Threaded lugs 23 also project from the open end of the housing I5, pass through the openings in the cover plate 20 and nuts M are threaded onto the lugs for securing the cover plate 213 in position. A gasket 25 provides for sealing the cover plate against leakage.

The pipe M has an upper end in open communication with the chamber IT, as shown at 26. The lower end is perforated, as shown at 21, and is disposed adjacent the bottom 28 of the container Iii. A sleeve 30 embraces the pipe or tube Hi intermediate its ends and is provided with a winged nut 3| threaded on the upper end which i is adapted to securely lock the sleeve to the tube I l and seal it against the loss of fluids at the outer end. The inner end of the sleeve is threaded at 32 into the opening l2 and a split collar 33 of well known construction is adapted to not only secure the sleeve to the top H but for aiding in sealing a sleeve against the loss of fluid from the container it.

A branch pipe 35 is in open communication with the annular space in the sleeve which is between the tube i l and sleeve 30 and this annular space is in open communication with the interior of the container above the liquid therein through the opening l2 in the top H. A check valve is housed at 3B and is adapted to permit fluid in the chamber It to enter the: space in the container l0 but will prevent any liquid from passing through the container to the compartment or chamber.

Formed integrally with the cover plate [9 is an elongated boss 40 which has a pocket M in open communication with the chamber or compartment l6 through the passages 42. A tube 43 connects the pocket 4| with a nipple 44 which is provided with a safety valve 45 which will release gas pressure in the compartment l6 when said pressure is raised above a predetermined degree. A flexible tube 46 connects the nipple 44 with the branch pipe 35.

One end of the compartment or chamber I1 is provided with an opening 50 which is in communication with the discharge pipe 5| having a rotary valve 52 which is controlled by a pivoted operating member 53.

The operation of my device is as follows: Congealed carbon dioxide is placed in the compartment l6, and this is popularly known as dry ice, after the tube M has been forced through the opening in the top H of the keg or container l0 and the sleeve 3|] has been secured in place.

As the congealed carbon dioxide gas absorbs heat gas will be produced and this gas enters the pocket 4| through the passages 42 and then finds its way to the confined space within the keg Ii! above the liquid in the keg or container. When sufficient gas has been produced it will exert a pressure on top of the liquid and force the liquid through the passages 27 into the pipe 54 whence the liquid will find its way into the compartment l1.

Due to the evaporation of the dry ice or congealed liquid carbon dioxide, heat will be absorbed and thereby the chambers l6 and I! will likewise be cooled so that the liquid from the keg or container H) which has been forced into the compartment I1 will be chilled and is therefore ready for dispensing.

The compartment l6 will be of such capacity that it will cool the liquid of the keg H] as it enters the compartment l1 and as the liquid is being dispensed.

I claim:

In a device for cooling and dispensing liquids from a sealed container comprising a casing divided into a horizontally disposed refrigerating chamber and adapted to contain solid carbon dioxide and a horizontally disposed dispensing chamber in heat interchange relation with the refrigerating chamber, one end of the casing being open, a separate closure for the open end of each chamber, the closure for the refrigerating chamber being provided with a plurality of gas passages, a conduit formed integrally with the said closure with the passages connecting the conduit with the refrigerating chamber, a discharge pipe adapted to enter the container and in open communication with the dispensing chamber, a sleeve secured to the discharge pipe and a tube connecting the sleeve with the conduit, the dispensing chamber being isolated from the refrigerating chamber.
